Electronic Devices & CircuitsFET & MOSFET

A common-source FET amplifier normally produces approximately what phase relationship between input and output voltage?

  • A0 degrees
  • B90 degrees
  • C180 degrees
  • D270 degrees only
Report an error
Correct Answer: C. 180 degrees
Explanation: Like the BJT common-emitter stage, the common-source FET voltage amplifier is inverting and produces approximately 180 degrees phase reversal.
Reference: Standard FET amplifiers: common-source stage
